Nigerian senior national team coach, Gernot Rohr has identified the only thing that may stop the Super Eagles from doing well in the 2018 World Cup in Russia.
The coach warned against another pay strike at the World Cup if the country hoped to improve on their previous outings at the global tournament.
Recall that at the 2014 World Cup, the Super Eagles skipped a training to protest the non-payment of bonus for qualifying for the tournament.
Rohr said Nigeria can improve on their best World Cup performance of a Round-of-16 by preparing early and better too.
The coach called for early preparation as well as ensuring money issues are sorted out well in advance.
FIFA will be paying Nigeria a total of $12.5 million for qualifying for Russia 2018 with $2.5 million of this amount paid for the Eagles to prepare adequately for the football showpiece.
The team will earn more cash should they reach the knockout rounds of the tournament as they have done in 1994 and 2014.
Rohr told reporters that, "If we want to do something at the World Cup, we have to prepare well. We want everybody who wants to be part of the team to show the same solidarity we currently have in the team.
"More importantly, we don't want the issue of money to be a problem.
"The issue of bonuses and allowances, which are the usual African problem we see during the World Cup, must be avoided.
"Such issues will be bad for our preparation. I have told my officials and the federation president that all (such issues) be cleared before the start of the competition."
